Uniplanar nystagmus associated with perceptual and cognitive visual dysfunction due to presumed focal ischemic occipital cortical atrophy: a missed diagnosis and new observation [PDF]

open access: yes, 2012
Uniplanar nystagmus has been described in relation to pathology of the brain stem, retina, optic nerve, sensory visual deprivation, periventricular leucomalacia, and drug toxicity.

Optic nerve sheath meningiomas: prevalence, impact, and management strategies

open access: yesEye and Brain, 2018
Optic nerve sheath meningiomas are rare benign neoplasms of the meninges surrounding the optic nerve. They are a significant cause of morbidity. While the mortality rate is practically zero, these tumors can blind or disfigure patients.

ATF3 upregulation in glia during Wallerian degeneration: differential expression in peripheral nerves and CNS white matter [PDF]

open access: yes, 2004
Background: Many changes in gene expression occur in distal stumps of injured nerves but the transcriptional control of these events is poorly understood.

Differences between Proximal versus Distal Intraorbital Optic Nerve Diffusion Tensor Magnetic Resonance Imaging Properties in Glaucoma Patients [PDF]

open access: yes, 2012
Purpose. To analyze in vivo the diffusion tensor magnetic resonance imaging (DT-MRI) properties of the intraorbital optic nerve at two different levels: Proximal to the optic nerve head (ONH) and distal to the ONH at the level of the orbital apex in ...

Evidence for Cerebrospinal Fluid Entry Into the Optic Nerve via a Glymphatic Pathway.

open access: yesInvestigative Ophthalmology and Visual Science, 2017
Purpose The purpose of this study was to determine whether cerebrospinal fluid (CSF) enters the optic nerve via a glymphatic pathway and whether this entry is size-dependent.

The thickness of the retrobulbar portion of the optic nerve in Graves ophthalmopathy measured by ultrasound [PDF]

open access: yesSrpski Arhiv za Celokupno Lekarstvo, 2009
Introduction. The clinical diagnostic of Graves ophthalmopathy is based on the association of ocular signs and the disease of the thyroid gland. The evolution of the disease involves the development of eye globe protrusion, extraocular muscle thickening ...

Role of heparan sulfate proteoglycans in optic disc and stalk morphogenesis [PDF]

open access: yes, 2014
Background Heparan sulfate proteoglycans (HSPG) are important for embryonic development via the regulation of gradient formation and signaling of multiple growth factors and morphogens.

Multidimensional scaling of D15 caps: Color-vision defects among tobacco smokers? [PDF]

open access: yes, 2004
Tobacco smoke contains a range of toxins including carbon monoxide and cyanide. With specialized cells and high metabolic demands, the optic nerve and retina are vulnerable to toxic exposure.

Predictions of Optic Nerve Traction Forces and Peripapillary Tissue Stresses Following Horizontal Eye Movements.

open access: yesInvestigative Ophthalmology and Visual Science, 2017
Purpose To use finite element (FE) analysis to predict the optic nerve sheath traction forces that act on the optic nerve head (ONH) following horizontal eye movements, and the resulting stress levels in the peripapillary connective tissues of the ONH ...
